Scientists advise caution. Those who use white, pink, or brown noise to sleep should be especially careful. Just like the brain, their hearing needs to recover from its exertion. "Hearing is an active process, where metabolic waste products are produced that can damage hearing in the long term. Actually, the best time for the hearing to break down these metabolic waste products and, so to speak, clean up is at night," says Basner. The sleep researcher therefore recommends finding a volume that is comfortable for you personally, but not stressful. There is no recommended volume, but some studies recommend a volume of around 40 decibels for young children. Basner also recommends using a timer that turns the noise off after a certain period of time. This allows you to enjoy the desired positive effect for falling asleep while avoiding potential negative consequences. Anyone who wants to try the noise can find videos and playlists with titles like "White Noise," "Pink Noise," and "Brown Noise" on YouTube and relevant music streaming services like Spotify. Ultimately, however, according to sleep researcher Basner, more research is needed to find out whether the sounds are good or bad overall. https://www.tagesschau.de/wissen/forschung/rauschen-schlaf-100.html Published on 12apr2023
